You don't need to copy the entire analysis, as your analysis will be derived from the `DenseForwardDataFlowAnalysis` anyway you can do:
```
MyAnalysis::processOperation(Operation *op) {
    if (something)
        return success()
        
    return DenseForwardDataFlowAnalysis::processOperation(op);
}
```
